relation 69, afstationalry' member. the draw ngs, 10.indicates a door which adapt ed to be hingedly mounted in a mannernot shown f i-nthe drawings. but which is Well understood in the art. This door 10 is adapted to befihiounted on the usual jamb'construcQ tion the fragment vof jwhich is illustrated in tlie..dravvings and which is indicated by 11. In the embodiment of the'invention shown in the dr'a'vvingsfthe jainb ll includes a lip 12 against Whichthe edge 13 of the door is adapted to abut and it is to be understood that the door is to be mounted such'thatv it Will "swing away from the lip 12When it is inovedto open'position.

In the 'jamb' construction ll atlthe point best illustratedin the drawings, an opening .14 is provided. This opening 14 may have thejlatch bolt openingusually provided in jarnb" constructions although desired an additionalppening maybe provided. In the present instantthe jamh is recessed as indi- 'catedat115 on the surface on which the opening 14 opens and a face plate 16 is mounted in this" recess portion which has an'opening provided therein that is adapted "to be aligned Withithe opening l l One of the eleinents of mynnproved latch-J ing device is indicated generically by 17 in the "drawings and includes a relatively flat portion 18. ."Arrang ed to extendoutwardly. from the/ portion 18 .fI'OIH' OIIBIfaCG thereof 7 is aplate'19.' At'the endof the'portion118 opposite that from which the plate 19 ex: tends a p'ortion20-is struck frorn said Por- 35 tion 18 so asto extend at-right anglesthereto as lSlllLlStI'ittQdilIl Figs. lfand 2'in the drawings. 'The outwardstrikingoftheportion20 creates anopening 21 in themember18; A1 ranged in the members; 18 adjacent the out- 99 v'vardlyiextendingplate 19,"ap1ura-lity 0f hol'es21, are provided which are preferably arra n gedvin themanner shown best in Fig. 2. The utilitfy'iof these openings Willbe described more fullyhereinafterfl i T i Ad aptedto co-operate with the member 17 is a member generically indicated loy,23 'aI1'd- -v this member is formed fso as to be 7 substantially' .ui-shapedi 1 .It "comprises an elongated "bight poftioniz i and armpbrtions25and26 1 r which are adapted to extend at right angles to said portion 24. Arranged at substantially the mid point of the portion 24 is an opening 27. A leaf spring member 28 is provided which has one end portion thereof connected to the outer end of the arm 25 as indicated at 29 in the drawings. The other end portion 30 of the leaf spring member 28 extendsthrough a recess 31 provided on'the outer edge of the arm 26 and this leaf member is connected to 'the arm 26 adjacent theoute'r end thereof as indicated at 3 As is best illustrated in Fig. 1 the leaf spring member 28 is arcuate in form and is arranged such that at substantially the mid a continuationofthe post 34 is arranged such that the post 34 is projected through. this opening 33. Aicollar 36 is disposed around the post 3%; and is connected thereto between the leaf'spring member 28 and the portion 24 soas to retain the latching member in position.

When positioned in in-operativeposition so as to be ready for shipping or when not in usethe member 23 has the arms and 26 thereof disposed between the arms 21 and 19 of the member 17 and a portion 24 is arranged so as to'be disposed opposite from the portion 18 and the portion of the leaf spring member 28 isextend'ed through an opening 37 provided in the portion 19 at the juncture thereof with the portion 18. In this manner the portions17 and 23 are nestedtogether and this'is clearly illustrated in Fig. 4. When it is desired to install the latching device in latching position with respect to a door or other hingedly mounted member the 'endpor'tion of theplate 18 is disposed between the'edge of the door and the amb and the lip 20 isinserted into the opening 17 in a manner illustrated in Fig. 1. The door is then moved to closing position which is illustrated in Fig.1 and the vmember 23 is arrangedsuch that the outer face ofportion 23 is arranged in abutment with the outer face of the portion 18 thus the leg 25 will be disposed in abutment Withthe face of the door. The finger portion is then gripped so asto retract theiboltmember 34 and after the plate member'23 "isproperly positioned this finger portion 35 is released and" therefore thebolt member 35 will pass through one "of the openings 22 whichare disposed'such that one of these openings-willv always be in position suchthat the bolt-member 34 may pass therethrough, The "bolt member 34 is inserted through the opening 22 whichl'will cause tight engagement. of. the foot portion 25 with "the face of the door. me that a. wedgingaction will be present and this arrangement serves to effectively retain the member 23 in position. Due to the tension of the spring 28,-the bolt member 34: will be retained in position and it is therefore apparent that an attempt to move the door 12 such that the portion 13 thereof will disengage the lip 12 will tend to tighten the engagement of the portion 25 with-the face of the door and will tend to tighten the engagement of the lip 20 Withthe Wallet-the recess and therefore the door will be held against opening movement.

While I have illustrated and described the preferredform of construction for carrying my invention into effect this is capable of variations and modifications without depart- .ing from the spirit of the invention. I,

In combination with a door and a jamb therefor, means for latching. said door against openingmovement including a plate having a leg extending from one face thereof, said plate being disposed'between said door and said jamb with saidprojection in 'an opening in said jamb, a substantially U- shaped member including an .elongatedbight portion, a leaf spring having theend-portions thereof secured to the ends of the limbs of said U-shaped'member andhaving the intermediate portions thereof disposed toward said bightportion, said bight portion havingan elongated transversely extending slot formed therein, said spring member having an elongated transversely extending slot formed thereirrin alignment with said first named-slot, a. securing member, said securing member including a post portion extended throughsaid slots, means: for connecting said securing member to. said spring member whereby, said spring member. will, urge said securing member in the direction of said bight portion, said plate having a plurality of openings formed therein --whereby when said U-sha-ped member is disposed with one of the limb portions in abutment with the face of said door said securing member may be extended through one of said openings' to interconnect said plate and said U- shaped memb'ertoprevent opening move-. ment of said door.
